Thanks Marcia. My boys still talk about their party. I'm sure your son will love the theme too. To get the schoolbus to stand up I leaned it against 2 Ikea kids chairs. I marked where the legs and top of the chair were on the back of the bus and drilled holes. I used zip ties to attach the chairs to the plywood bus. It worked out perfectly because the guests had somewhere to sit and made the photos more natural. I wish I had third chair for the middle window.

Thank you for take time to answer me. I am not crafty at all so... I think I will try to make one bus of a cardboard instead of plywood. It should last for a couple of hours, right? I hope so. Wish me luck! :)
